To all whom it may concern:

Be it known that I, GEORGE E. MALTBY, a citizen of the United States,resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and-useful Improvement in Track Constructions, of which.the following is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from'other inventions.

' My invention relates to track constructions, its obj ect being toprovide a rail which will be economical of manufacture and efiicient inthe performance of its function.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawing and the following description, set forth in detailcertain means embodying my invention, the disclosed means,however,constituting but one of various mechanical forms in which the principleof the invention maybe employed. In said, annexed drawing -Figure 1represents a cross-sectional view of a track construction embodying partof my invention.

Fig. '2 represents a cross-sectional view of a rail embodying anotherpart of my invention. Fig. 3 represents aside elevation of a fragmentaryportion of the track'construction, partlyin longitudinal section. Fig. 4

represents across-section of the parts illustrated inFig'. 3. Fig. 5represents a, view similar to that of Fig. 3, showing a modified methodof eifecting abond in the track constructionembodying my invention. Fig.6 represents a cross-section of'the parts shown in Fig. 5. r g

My invention, as illustrated by Fig. 1, comprises a track consisting ofabutting rails 1, eachcomprising a tread portion '2, two lat- 'eral legs3,3, each leg formed with a lat;

erallyextending flange 4, thereby forming an interior space5, open atthe bottom. -The abutting ends of the rails-rest upon atie- 'platefi,"and'within the space 5. and extending from one railto the next, is asplice bar 7. The splice bars are provided with suitable apertures 8registering with apertures l 9 in the rails, through which bolts 10 arepassed and secured by means of nuts, 11.

I The splice barsareg'iven' sections similar and equal in area to theinterior; space I Specification of Letters Patent. Pate ted Feb, 29,1915; Application filed; October 5, 1915. SerialNo. 54,132. I

formed so that they completely fill such space at the oint. The weakestpart of the track is therefore supported and reinforced,

as willbe apparent. Furthermore the splice bars by being located'withinthe interior of the rails do not become detached therefrom, even whenthe nutsand bolts become loose, and remain in place as longas the boltsdo not fall out of, the holes. Even should all of the bolts be removed,the splice bars will retain their position for asufiicient length oftime to enablethe track to be repaired and in'the meantime retain theabutting ends in their proper alinement. In addition, the U-shaped formof rail may be rolled with greater advantage than the forms heretoforeused, as I have found that a maximum of homogeneity of molecularstructure is obtained when this form of rail is rolled.

I have found, however, that the simple U-shaped form of rail shown inFig. 1 may be modified as illustrated in Fig. 2, to advantage. In thismodification, I have provided an interior depending web 12 which websintersect the interior space formed by the abutting rails and thus abutat the ends of the latter. These flanges divide the interior space intotwo portions and instead of employing a single splice bar, I use twosplice bars, each fitting snugly the two parts ofthe interior space, asshown in Fig. 4. As before, the two splice bars rest upon the tieplate6. I

,The employment of the web 12 increases the moment of inertia of therail, as will be apparentto anyone skilled in the art and adds thisadvantage to the advantages already indicated in connection with thatform of construction illustrated by Fig.1. r The structure lastdescribed may be further modified, as shown in Fig. 6, by making.

the splice bars integral with the tie-plates.

When it is desired to bond the rails, the

In the form illustrated in Fig. 6, I.have

shown, a modification of the device to conform with a change of locationof the point ofweld'ing the bond. In this case the bond ,is welded tothe top portionof the web and pose and for receiving the bond itself. In

' such space; of splice bars in said space upon this instance, the web12 may extend toi the tie-plate, as'shown. 1 1

Having fully. described my invention, what I claimand'desire to secureby Letters Patent is y o 1. As a new article of manufacture a railhaving a double U-section, and compris ing' an integral head .or'tread-portion, two 1 lateral andsubstantially parallel side webs, thelower end of each such side webbeing formed with an integral laterallyextending flange havinga lower fiat contact surface, together with acentral integral and downwardly extending web portion.

2. The combination with two abutting V rails forming an interior space,each'rail provided wlth an interior web intersectlng opposite sides ,ofsaid web and secured to K said rails. V .7 V I i 3. The combination oftwo abutting rails forming an interior space, each formed with aninterior web' intersecting the latter; a f

tie-plate on which the abutting rail end pertions are supported; splicebars within said space, upon 'OPPOSite sides of said web and secured tosaid rails. V: r 4. 'The'combination of twoabutting rails forming. aninterior spaceand with an in- V terior'. web lnterseoting said space; at 'eplate on which the abutting rail end portions'a're supported; andsplice bars in said space uponopposite sides of said web, said- 7 barsbeing integral with'said tie-plate and;

securedto said rails;
